The Famous Hot River Hike
Reykjadalur, meaning "Steam Valley," offers one of Iceland's most unique experiences - hiking through a geothermal wonderland to bathe in a naturally heated river surrounded by steaming hot springs and fumaroles.
Reykjadalur offers something truly unique in Iceland: the chance to bathe in a naturally heated river flowing through a geothermal valley. Hot water seeps up from underground and mixes with cold river water, creating comfortable bathing temperatures along stretches of the riverbed.
Wooden boardwalks and changing screens have been installed to protect the fragile landscape while providing visitors with basic facilities in this otherwise wild setting.
The journey is as spectacular as the destination - a moderate 3.2km hike through ever-changing geothermal landscapes.
